Summary
In the allegory of Plato’s cave, prisoners see the world only through shadows. Extending this metaphor to AI, AI models are the prisoners and the shadows are streams of data. Are all models converging on a singular representation of reality? On this week’s episode of The Quanta Podcast, host Samir Patel speaks with staff writer Ben Brubaker about how, despite being trained on entirely different data types, different models can somehow develop similar internal representations. This topic was covered in a recent story for Quanta Magazine.
Each week on The Quanta Podcast, Quanta Magazine editor in chief Samir Patel speaks with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.
Audio coda: The Cave: A Parable Told By Orson Welles, Produced by Counterpoint Films, directed by Sam Weiss, and illustrated by Dick Oden. https://www.acmi.net.au/works/65888--the-cave-a-parable-told-by-orson-welles/

| 0:00.0 | Have you ever had the urge to sneak behind the cordoned off areas of a museum? |
| 0:05.7 | Or roam the halls after closing time? |
| 0:08.7 | The Smithsonian's flagship podcast, Side Door, will sneak you behind the scenes of the world's |
| 0:14.5 | largest museum and research complex. |
| 0:17.5 | Come learn about the ghosts that supposedly walk the museum halls after dark. |
| 0:21.6 | How a train robbery gave rise to criminal forensics, |
| 0:24.6 | why leeches are actually the coolest thing ever, and how to get away with murder in the Arctic. |
| 0:30.6 | Maybe. |
| 0:31.6 | You'll discover stories of history, science, art, and culture you won't find in a display case. |
| 0:42.1 | You can listen to Side Door wherever you get your podcasts, or find us online at sI.edu slash Side Door. |
| 0:49.3 | It's satisfying when, in the course of doing these modern science and math stories, we get |
| 0:59.0 | the opportunity to cite thinkers from the deep past. |
| 1:03.1 | Scientific insights have arisen all over the world, but in Western thought at least, the |
| 1:07.2 | ancient Greeks come up a lot. |
| 1:09.2 | Pythagoras and Aristotle and Epicurus. |
| 1:12.6 | They had ideas around math and the universe and atoms and the brain. |
| 1:17.6 | So it shouldn't surprise us when Plato recently made a guest appearance in a story about artificial intelligence. |
| 1:23.6 | Plato had this idea that there are idealized, perfect forms that provide the structure for all the messiness of reality. We can recognize a lot of different things as tables because there's an essence of tableness that they share and that we can recognize in them. Maybe you see where we're going with this. |
| 1:44.5 | What does AI think is a table? |
| 1:47.1 | And do different kinds of artificial intelligence |
| 1:49.4 | arrive at the idea of a table in different ways? |
| 1:52.9 | How would we even know? |
